The equipment room body is made of high-quality corrugated board, modular design, and high-strength bolts are used for mobile connection and disassembly. There is a light rail track installed on the ground, and the trolley can enter and discharge the material. The trolley can be designed and manufactured according to the condition of the parts to fix and rotate the sandblasted parts. Explosion-proof LED lights are installed on the top of the room. The sandblasting status can be observed through the window at the artificial door. The pellet recovery system can be recovered by wind or elevator. In order to avoid the high efficiency and smoothness of the pellet recovery system, the pellets should be less than 220 mesh as much as possible. The equipment is equipped with a V200 shot blasting system to ensure the continuity and stability of the shot.
